Incorrect Repository URL for OracleLinux 7 Server

[rexxin-de]

Please provide a brief summary of the bug

Following the instructions from https://adoptium.net/installation/linux/ does not work for OracleLinux 7 because yum/dnf variable "releasever" differs from the https://packages.adoptium.net/ path.

Please provide steps to reproduce where possible

The following instructions from https://adoptium.net/installation/linux/ were performed:

# Uncomment and change the distribution name if you are not using CentOS/RHEL/Fedora
DISTRIBUTION_NAME=oraclelinux

cat <<EOF > /etc/yum.repos.d/adoptium.repo
[Adoptium]
name=Adoptium
baseurl=https://packages.adoptium.net/artifactory/rpm/${DISTRIBUTION_NAME:-$(. /etc/os-release; echo $ID)}/\$releasever/\$basearch
enabled=1
gpgcheck=1
gpgkey=https://packages.adoptium.net/artifactory/api/gpg/key/public
EOF

yum install temurin-8-jdk

Expected Results

Package temurin-8-jdk should be installed via yum.

Actual Results

yum exits with error:

# yum install temurin-8-jdk
Loaded plugins: ulninfo
https://packages.adoptium.net/artifactory/rpm/oraclelinux/7Server/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
Trying other mirror.

 One of the configured repositories failed (Adoptium),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:
[...]

failure: repodata/repomd.xml from Adoptium: [Errno 256] No more mirrors to try.

The problematic part of the adoptium.repo is here:

baseurl=[https://packages.adoptium.net/artifactory/rpm/${DISTRIBUTION_NAME:-$(](https://packages.adoptium.net/artifactory/rpm/$%7BDISTRIBUTION_NAME:-$(). /etc/os-release; echo $ID)}/$releasever/$basearch

Unlike RHEL or CentOS in OracleLinux Server $releasever does not evaulate to 5, 6, 7 etc. but "7Server".

It would be nice if you could make the packages from
https://packages.adoptium.net/ui/native/rpm/oraclelinux/7/
also availabe under
https://packages.adoptium.net/ui/native/rpm/oraclelinux/7Server/

Docker seemed to have the same problem (docker/for-linux#1111) that's probably why they added 7Server, 7Client and 7Workstation to the repository; see https://download.docker.com/linux/centos/.
